SPECIFICATION forming part of Letters Patent No. 768,159, dated August23, 1904.

Application filed April 13, 1903.,

To all whom it may concern.-

Be it knownthat I, EDWARD O. vSUoKER'r, a citizen of the United Statesof America, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inLoose-Leaf but will lie flat against the covers.

It is also an object of the invention to so construct the device thatany or all of the leaves may be quickly and conveniently removed andothers inserted-and to providece'rtain other new and useful features,all as hereinafter more fully described, reference beinghad to theaccompanying drawings, in which Figure 1 1s a perspective view showingthe device open and the leaves removed. Fig. 2

is an enlarged end elevation of the same with the leaves in place; Fig.3, a perspective view showing the book closed. Fig. 4 is a perspectiveview showing a modified construction with the device open and the leavesremoved; Fig. 5, an enlarged transverse section of the same through oneof the binders with the leaves in place; Fig. 6, an end View of thesame, showing the book closed; and Fig. 7 is adetail showing detachedportions of the back, cover, and hinge members in perspective.

As shown in the drawings, A A arethe 'covers, and B the sheet-metalback, consisting of a curved backportion B",which may be formed withornamental and strengthening ribs B and otherwise ornamented andlettered, and

- also of side flanges B extending parallel with .each other and eachformed with an eye B by rolling the metal outward at the outer edge ofthe flange, said eyes forming one part of hinges C for securing thecovers A and binders D to the back. The covers are hinged to the back byproviding eyes E, formed of sheet metal,

Serial No. 152,346. (No model.)

with leaves embracing the covers and riveted thereto, and the eyes B aresevered from their flanges B for a short distance at each end, so thatthey may be embraced by the eyes E and serve as the other member orhollow pintle B of a hinge to unite the covers to the back. The coversare also each provided with .a double-eye member E midway between theirends, and the eyes B 'are cutaway opposite the eyes E to allow the sameto project into line withthe eyes B and also to allow the ends of one ofthe binding members D to project into the space between the eyes of thedouble members. The eyes B are also cut away'near each end'to receivethe ends of the binding members D, which are provided with transverseopenings D to receive the rods or pintlesF of the hinges O, which rodsare passed through the eyes B, the double eyes E, and the openings D inthe binders, thus pivotally and detachably securing the ends of thebinders D to the upper ends of the flanges of the back or at the pointwhere the leaves bend when the book is opened. One end of each rod F isprovided with a milled head, and its opposite end is screw threaded toengage a screwthreaded opening in a block F, secured in one end of eacheye B.

The leaves G are perforated at three points near one edge to receive thethree binders D, which are curved slightly throughout their length, sothat the center leaves will be raised higher than those nearer theflanges when the book is opened, and thus allow the leaves to 'lie'moreclosely against the covers. The leaves may also be scored across, asshown at G, so that they will bend with a more abrupt angle.

In certain instances it may be found desirable to use the form of bindershown in Figs. 4 and 5, in which a coiled spring D is used instead of asolid curved bar, and this spring is preferably covered with a piece ofrubber tubing D or other suitable covering, this providing a flexiblebinder which will yield laterally, and thus allow the leaves to he morenearly flat upon the covers than would be possible if a solid bar wereused.

When the flexible binders are used, it may be found desirable toconstruct the back and hinges as shown in Figs. 4, 5, and 6,the backbeing formed of sheet metal with side flanges, as before; but, insteadof the hinge-eyes being formed on the back, eyes H are secured to theedges of the covers A, and these eyes are cut away to receive the endsof the binders, which are pivotally attached to the covers by thehinge-rods or pintles which pass through the eyes H and the loops D onthe ends of the springs D forming the binders. The back-is formed withend portions 1, and these ends are provided with transverse slots 1,through which the rod F passes to hinge the covers to the back, theslots in one end being provided with blocks1 ,having screw-threadedopenings to receive the screw-threaded ends of the rods. The coversbeing hinged to the rods, said rods will be moved toward each other inthe slots 1 by the bending of the binders when the book is opened, thusallowing the binders to bend more than they otherwise would.

In this construction any or all of the leaves may be very quickly andeasily removed or others put in, it being only necessary to turn one ofthe rods by its milled head until it is disengaged from thescrew-threaded opening in the block F, when it'may be pulled out of theeye B and the back turned away from the leaves, which may then be liftedoff the binders or new leaves slipped on. The device is also veryinexpensive, as the parts are few and easy to make.

Having thus fully described my invention, what I claim isl. Thecombination with a back and covers, of a series of flexible binders, andmeans pivotally connecting the back, covers and binders whereby the endsof each binder are allowed to move toward each other as the binders areflexed by the opening of the book.

2. The combination with covers and a back, of a hinge connection betweensaid covers and back consisting of hollow pintles and a hinge memberembracing said hollow pinl'les, binding members having openings in theirends, and rods passing through the openings in the binders and thehollow pintles.

3. The combination with covers, of a back provided with side flangesformed with eyes at their upper edges, hollow pintles formed by severingthe eyes from the flanges fora distance at each end, eyes on the coversenibracing said pintles, binding members having openings in their ends,and a rod extending through the binders and hollow pintles.

4. The combination, with covers, of eyes on said. covers, a series ofbinders having openings in their ends, a back provided withside flangesoutwardly turned at their edges to form eyes, said eyes being cutaway toreceive the ends of the binders and severed from the flanges at each endto form pintles for the eyes on the covers, blocks secured in one end ofeach of the eyes on the back flanges and having screw-thremledopenings,and rods each extending through the eye on one flange and theopenings in one end of the binders and having a screw-threaded end toengage the screw-threaded opening in the block.

In testimony whereof I ailix my signature in presence of two witnesses.
